dm_test_irq_...bles_polling(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_irq_suspend_disables_polling(9) 💅

okay so this page is straight out of the Kernel API Manual bestie, and it's literally about one very specific little test. slay. let's get into it 🫶

🌸 NAME 🌸

dm_test_irq_suspend_disables_polling — Test suspend disables KMS polling ✨

🧚 SYNOPSIS 🧚

void dm_test_irq_suspend_disables_polling (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — The KUnit test context 💖 (that's it, that's the whole argument, she's low maintenance)

🔥 DESCRIPTION 🔥

so the whole point of this test, no cap: with KMS polling active, suspend must take the poll-disable branch. periodt.

and here's the detail that matters — drm_kms_helper_poll_disable only cancels the poll work. it does not clear anything else. it leaves the poll_enabled flag set. 😭

like bestie, that flag doesn't get cleared here at all — it's cleared later, by drm_kms_helper_poll_fini. don't @ me, that's just how it works. 💀

🦋 SEE ALSO 🦋

Kernel file (go read the source, iykyk):

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_irq_test.c

and now, the icon herself — the full squad of related pages, every single one, in order, because we don't skip entries in this house 👑

and that's the whole page bestie, you ate that 🍓💜

okay so like, tiny sign-off realness: this came from ./drivers/gpu/drm/amd/display/..., dated October 2026, and the page answers to the name dm_test_irq_...bles_polling(9) (yes the header truncates it, she's mysterious like that 😭✨). mwah, go read the source, ily 🎀🦋
